use and maintenance

1. Sampling:

Connect the air inlet on the back of the instrument to the sampled load with a suitable hose, press the microcomputer ON/OFF button, and the display screen will show "0:00". Then press the MIN button to select the desired time. The maximum time for this button is 59 minutes. If 59 minutes is not enough, press the HOUR button again, and the maximum time for this button is 15 hours. When the time is selected, press the ON/OFF button again to start sampling. At the same time as the sampling pump is working, the computer enters a countdown state. When the computer display screen shows "0:00", the host automatically cuts off the power by the computer program and the buzzer starts to alarm for 20 seconds. After 1 minute, the "0:00" character in the display screen will also disappear, and the power in the computer will also be cut off.

To reset or shut down in advance, simply press and hold the ON/OFF button for 2 seconds to enter the reset or shutdown mode, and the display screen will show "0:00".

2. Charging:

Insert the AC power supply into the instrument's 220V AC input terminal and the mains power respectively. The instrument is in a shutdown state, and a full charge takes about 14-16 hours (standard charging time). It can work continuously or cumulatively for about 3 hours each time it is fully charged.

The battery voltage indicated by the voltmeter during sampling and the battery voltage during charging. The fully charged voltmeter indicates around 12V.

Attention: When the voltage of the internal battery is below 8V, the battery should be charged. If it is not used for a long time (more than 3 months), it should be recharged to ensure the service life of the high-energy cadmium nickel battery. During the sampling process, a safety bottle should be connected to protect the safety of the air pump and gas circuit.
